IVR Mazzega was one of the best furnaces in its day. Two of its master glassblowers were Ermanno Nason and Pino Signoretto. They made traditional style glass mostly and a good many animals. The animals go for a premium because it can be difficult to find ones with labels. The animals have the standard forms and poses, but are sought after. Wish I had a few dozen of them.

I found these two birds last week on Ebay and found them interesting. They favor my birds by Franco Moretti (the technique used and not the shape of them). The rooster labels are on both and it looks like the labels have the letters CC by the rooster. I haven't seen the rooster labels with CC on them before. I do wonder if Franco Moretti made them. The murrine eyes kind of favor some of his murrines also. I just thought I would link them to this thread.

P.S. - I originally thought that Franco Moretti pieces were all signed but I recently bought a paperweight that is FM and it is not signed and only has a plastic label. I do wonder about the birds in the above link if they are really signed under the label or not.
